Description

Deguang Song's team found that gut friendly germs make ACh in vivo, teaching the mucus immune system. Screening one hundred friendly strains in germ-free mice and in culture showed in vivo and in vitro profiles switching on G-protein-coupled sensors in varied ways. Host breakdown, germ rewiring, and dietary change drove the differences.

Several strains, including early-life Bifidobacterium and a probiotic Pediococcus, turned dietary choline to ACh. The key enzymes were found, and a cut-out strain was built. Mice settled with ACh-producing Bifidobacterium breve made more gut IgA, revealing a germ nerve-signal route to immune training.
